It appears Google News is testing a new layout on its homepage. The new layout still uses three columns for categories, top stories and recent news. Departing from the traditional blue 'news-only' links, the new design includes video news and related opinion and news stories in the main results.
Google has always presented green links for alternate news agency stories and a link for all sources.
In the newly spotted layout the "all sources" link only appears beneath the top-most story. In-line with the link are icons for sharing. In line with the phased rollout of their social strategy, Google's new +1 button is still missing, but there are icons for Google Reader, Buzz, Twitter and Facebook.
Here're the screenshots Old vs. New Google News Layout:
